DDS was temporarily pinned to 4.1.0 because 4.2.0 triggered some test failures (see https://github.com/flutter/flutter/pull/147250). Those failures should be fixed by vm_service 14.2.2, so this unpins DDS and rolls both of these packages (along with devtools_shared, which is a DDS dependency). (If the bot updates vm_service before this is done, I can rebase over that will reduce the size of this PR to just a few files)
iOS Add2App Life Cycle Test
This application demonstrates some basic functionality for Add2App, along with a native iOS ViewController as a baseline and to demonstrate interaction.
The following functionality is currently implemented:
- A regular iOS view controller (UIViewController), similar to the default
flutter createtemplate (NativeViewController.m). - A FlutterViewController subclass that takes over the full screen. Demos showing this both from a cold/fresh engine state and a warm engine state (FullScreenViewController.m).
- A demo of pushing a FlutterViewController on as a child view.
- A demo of showing both the native and the Flutter views using a platform channel to interact with each other (HybridViewController.m).
- A demo of showing two FlutterViewControllers simultaneously (DualViewController.m).
A few key things are tested here (IntegrationTests.m):
- The ability to pre-warm the engine and attach/detach a ViewController from it.
- The ability to use platform channels to communicate between views.
- The ability to simultaneously run two instances of the engine.
- That a FlutterViewController can be freed when no longer in use (also tested from FlutterViewControllerTests.m).
- That a FlutterEngine can be freed when no longer in use.
